2/22/2017 – Maybe this is what Hou Yifan meant when she chose not play the 2017 World Championship. The top seed Ju Wenjun was caught completely unawares in the opening against Tan Zhongyi who pushed her off the cliff to qualify for the semis. Joining Zhongyi were Kosteniuk and Muzychuk. Harika had to hold a draw with black to qualify as well. But the experienced Nana Dzagnidze played exactly what the doctor ordered. Illustrated report.

The tournament saw one of its most dramatic days, in Tehran. The most shocking result being Ju Wenjun, seed number one, fresh from a great success at Gibraltar and a smooth run so far at the world championship, going down at the hand of her country-mate Tan Zhongyi.
On the white side of a Catalan, Ju Wenjun got confused by her opponent’s rare choice and obviously did not manage to respond properly.
Tan Zhongyi showed better understanding and put Ju Wenjun in a critical position as early as move 15.
Stuck with a difficult position and her clock ticking, Ju Wenjun caved in almost right away with 15. Ne5? as a result of which she lost the game and the match. A shocking outcome, as seed no.1 is out of the tournament in the quarter-final.

I talked a lot about Nana Dzagnidze’s resourcefulness but her performance today was another proof why she is a hard nut to crack.
She also forced Harika Dronavali into a difficult position.
Black to move and qualify for the World Championship Semis.
When Harika failed to find the correct counterplay, it was all Dzagnidze’s for the taking and she gradually converted her advantage. Tomorrow, Harika is up for her fourth consecutive tie-break!

With a lot at stake -maintaining a chance to reach semi-final or going home- Nana Dzagnidze once more showed us that why we should not condone her immense resourcefulness and high will to win.1.Nf3Nf62.c4e63.b3!?Nana avoids any opening debate as early as move three. Although, chess theory is developed that much that even in such cases there is a huge body of theory out there. However, the question is, is Harika prepared for it?d54.Bb2Be75.g30-06.Bg2c57.0-0Nc68.e3b6Ok, all these have been played zillions of times before.9.d4!?A rare choice.9.Nc3Bb710.cxd5Nxd511.Nxd5Qxd512.d4Qf512...Rad8?!black gets into some trouble after this natural move.13.Ne5Qd614.dxc5Qxc515.Nd7Qf516.e4Qg517.h4Qh618.Bc1g519.hxg5Qg720.e5Nb821.Nf6+Bxf622.exf6Rxd1

Anna Muzychuk has been the most consistent player in this tournament. Today, she got into trouble for the second time in this event after her second game against Kashilinskaya.
It seemed that the ex-world champion Antoaneta Stefanova is on the verge of converting her advantage into something meaningful in an unavoidable rook endgame but she made a couple of inaccuracies that let Anna to comfortably equalize and force a draw without any fuss.
Finally, Russian GM Aleksandra Kosteniuk got the better of her much less experienced, and indeed the biggest surprise of the event, Ni Shiqun, when the former’s bishop pair proved overwhelming in the rising endgame.
Chinese youngster Ni Shiqun played the tournament of her life.
Kosteniuk has always been in the forefront when it comes to making a style statement in chess tournaments...
...and the 2017 Women's World Championship is no exception.
